Andrus Adamchik closed CAY-1655.
--------------------------------
Resolution: Not A Problem
That explains it. "return new MyCustomAdapter(); " is how adapter is created.
There's nothing in this code that can perform injection. Looks at
DefaultDbAdapterFactory. It does this to create an adapter with dependency
injection:
return objectFactory.newInstance(DbAdapter.class, adapterType);
You might need to do something similar to instantiate your adapter with all the
dependencies coming from Cayenne.
I am closing this Jira, as there's no more indication that this is a bug and I
hope the above will work.
> Logger injection to JdbcAdapter subclass does not work
> ------------------------------------------------------
>
> Key: CAY-1655
> URL: https://issues.apache.org/jira/browse/CAY-1655
> Project: Cayenne
> Issue Type: Bug
> Components: Core Library
> Affects Versions: 3.1M3
> Environment: Windows 7, MS Access, JdbcOdbc driver
> Reporter: Wernke zur Borg
>
> I created a custom subclass of JdbcAdapter for some special handling with MS
> Access. It is instantiated by a custom DbAdapterFactory subclass, which is
> configured as:
> Module m = new Module() {
> public void configure(Binder binder) {
>
> binder.bind(DbAdapterFactory.class).to(MyCustomDbAdapterFactory.class);
> }
> };
> Now the application runs into a NullPointerException in
> org.apache.cayenne.access.jdbc.SelectAction.performAction() where it says:
> adapter.getJdbcEventLogger()... (line 171)
> This means that the injection of the JdbcEventLogger "logger" in my
> superclass JdbcAdapter has not taken place. It might be important that also
> SelectAction has been subclassed with a custom SelectAction.
> The problem does not occur when I comment the binder.bind(...) line out.
> Workaround: Instantiate a CommonsJdbcEventLogger in the custom JdbcAdapter
> and assign it to the logger (it is protected). But this logger is not aware
> of the log4j log level.
